Key Points

To compare tumour size and nephrometry scores in predicting surgical success after partial nephrectomy.
Observational analysis of nephrometry scores and tumour size
Evaluation of surgical outcomes including risk of AKI
Tumour size was found to outperform nephrometry scores in predicting surgical success
Lower nephrometry scores were associated with reduced AKI risk but had modest predictive performance

Abstract

Although lower R.E.N.A.L., PADUA, and SPARE NSs were associated with achieving surgical success and reduced risk of AKI, their predictive performance was modest and can be outperformed by a simpler and more objective measure, such as tumour diameter. Future studies remain necessary to re-evaluate the broader clinical utility of NSs in predicting surgical and functional outcomes, in addition to its original purpose as standardized tools for the anatomical characterization of renal tumours.
